What changes at a hosted table
A live round is a real croupier spinning a real wheel. The result is settled by the ball landing in a slot, not by a random number generator.
An RNG round is a software simulation. The result is settled by the studio's random number generator, on the server, in the same second the player commits the stake.
Live rounds resolve at roughly one per minute. RNG rounds resolve at roughly one per second. The player's decision is the same in both cases: pick a stake, commit, watch the result.
Why players choose live
Live tables have a hosted rhythm. The croupier announces the round, the player watches the ball, and the result takes time. A live session is naturally a 30 to 60 minute arc.
Why players choose RNG
RNG rounds run on seconds. A whole session can be a single round if the player wants it to be. RNG games like aviator, crash and plinko are built for the short decision.
